Where should I send a POST request?
I am writing an application using the Phalcon framework for PHP and I need to implement this functionality so that users can write posts on each other's walls. So with JQuery I would write:
function postMessage() {
var message = $("#messageBox").val().trim().replace(/\n/g, '<br/>');
if(message) {
$.post("// request handler", {msg: message, wall: {{ user.id }},
writer: {{ session.get('user')['id'] }})
.done(function() {
$("#messageBox").val('');
alert( "Message posted" );
})
.fail(function() {
alert( "Error posting message, please try again" );
});
}
}
And this script will be located at domain.com/user/foobar
My question is what (or rather where) my request handler should be. I thought about it a bit and asked my friend and suggested three options:
- Post to the same url as above, the script is located in (Ref.domain.com/user/foobar)
- Post to a different url that has a different action in the same controller as option 1 (ex. Domain.com/postmessage. Both options 1 and 2 are in the same controller, but they are different actions)
- Publish to API url (example api.domain.com)
Some of the pros I was thinking of were:
- Both options 1 and 2 can access the session variable, so I can check if the user is logged in or not. With option 3 I can't, but I can (unrealistically) hope no one tries to abuse the system and post with Fiddler or something without being logged in.
- Option 2 is slightly cleaner than option 1
- Option 2 and 3 provide central request handlers, so if I wanted to implement the same message in the wall writing system I would only need to copy the jQuery code and place it in a new view or page. With option 1, I need to copy the code from the custom controller and reverse it in the controllers for every new page.
Some cons I was thinking about were:
- Option 2 means I need to add additional routes to my router. More complex routing makes this possible. (And maybe slower ???)
(example
// Option 1
$router->add('/user/{id}',
array(
'controller' => 'user',
'action' => 'show'
)
);
// Option 2
$router->add('/user/post/{id}',
array(
'controller' => 'user',
'action' => 'writeMessage'
)
);
)
Which method is recommended and used?

Never assume that all of your users will be kind and smart, this is how people break the system. Check everything.
Typically: 1 route = 1 action If you don't have a route to send messages, adding one is the way to go. The route is like a simple "if" test, it will be done in a few nanoseconds.
